Definitions

  • the cylindrical portion 202 has an internally threaded front end 205.
  • the needle unit 3 includes an externally threaded needle seat 301 engaging threadably the front end 205 of the cylindrical portion 202 of the retaining seat 2, and a needle body 302.
  • the plunger 4 is movable within the barrel 1 between a front limit position and a rear limit position, and has an actuation rod portion 401, a piston 402 disposed movably and sealingly within the interior chamber 101 in the barrel 1, and a mushroom-shaped tongue 403 extending forwardly from the piston 402.
  • the tongue 403 engages a hole defined by the inward flange 204 of the retaining seat 2 so as to permit synchronous movement of the retaining seat 2, the needle unit 3, and the plunger 4 when the plunger 4 moves back to the rear limit position, thereby retracting the needle body 32 into the barrel 1.
  • the tongue 403 has a head that is formed with a slot 404 so as to permit the head to move into the needle seat 301 through the hole defined by the inward flange 103 and so as to prevent removal of the head from the needle seat 301 through the hole defined by the inward flange 103.
  • the retaining seat unit 20 is disposed in a front end of the barrel 10, and includes a unitary, rigid tubular main body 23 made of a plastic material and disposed within the barrel 10, and a unitary, tubular retaining element 24 made of rubber and fixed within the main body 23.
  • the main body 23 has a rear end that is formed with an integral outward flange 231, a front cylindrical portion 232, and four projections 236 (see Fig. 4 ) extending rearwardly from the outward flange 231.
  • the outward flange 231 of the main body 23 abuts against the shoulder 13 of the barrel 10.
  • the rear tongue portion 311R abuts against a rear end of the front inward flange 243 of the retaining seat unit 24 so as to retain the needle seat 31 on the retaining seat unit 20.
  • the rear tongue portion (311R) of the tongue 311 of the needle seat 31 has a frusto-conical rear end (311T), and the front clamping hole (243H) in the retaining element 24 has a frusto-conical front end (243T) so as to guide the tongue 311 of the needle seat 31 to engage the front clamping hole (243H) in the retaining element 24.
